The microvine provides new perspectives for research on berry physiology

Abstract

The berry developmental cycle was studied in a microvine parental line (L1) as well as in a segregating population of 130 genotypes (microvine x ugni blanc). Major solutes of oenological interest such as malic and tartaric acid, glucose, fructose, proline and potassium were analyzed. Gene expression profile was evaluated in post-véraison berries using Nimbelgen® microarrays.

The analysis of the developmental and molecular parameters validated the microvine as a model system for accelerated researches on berry development and physiology. Moreover, the small size of dwarf plants is a determinant advantage for experiments in climatic chambers.

Risk of late frost events in viticulture – temperature trends, phenological observations and spatial analysis based on digital terrain models in Franconia/Germany

In the course of global warming a general decrease of frost days per year and in spring can be stated. However, in viticulture this matter of fact doesn´t lead to a reduction of the risk of damages to grapevines by late spring frost events.

Estimating leaf area and leaf area index in VSP trained grapevines under different management systems (Vitis vinifera L. cv. Riesling)

The aim of this study was to validate and implement different non-destructive methods of leaf area and leaf area index (LAI) determination in VSP trained grapevines (Vitis vinifera L. cv. Riesling) in a field trial comparing different management systems (i.e. integrated (GAP) and two different organic (European Union Regulation 834/07) management systems).

Classification for timing of flowering and veraison of a wide range of Vitis vinifera cultivars with the “GFV” model

In viticulture, the timing of phenology is critical to optimize grape quality potential particularly so in cool climates. Flowering and veraison are key phenological stages for grapevines.
